Q:The number of drills and reamers for diameter from 1 to 20.. The more detailed, the better

At 12 of the diameter of the drill, the 600. reamer is 2. The others you push, the reamer must be 500 slow, the hole surface quality is not good

Q:Why reaming with reamer is the workpiece of ductile iron 500, the aperture will be smaller, and the aperture requirement is 9. After reaming, the reamer will not enter the hole. What is the reason why the hole is too small for the reamer to go in?

The precision can not reach. BECK-AUGUST world's top producer of precision cutting tools. BECK has 90 years of production experience and the most advanced production equipment, with its excellent product design and manufacture in the world leading drilling tool production, the non-standard cutting tools with the characteristics of high quality, precision has been widely used in automotive, aerospace and other fields.BECK single blade hinge adhering to the clamping tool not grind all the advantages, when the cutting tool wear or failure, as long as the replacement of the knife, a slight adjustment can be put into production. The fine adjustment mechanism can precisely and flexibly control the diameter of the blade and reverse the cone to meet the processing requirements. The whole process guide bar made of hard alloy, metal ceramic or artificial diamond can effectively control the treatment accuracy. I suggest you try some of your homemade reamers.

Q:In mechanical engineering materials, what are the materials of the reamer?

There are white steel reamer, carbide knife, as well as surface coating. The reamer also breaks the moving reamer and the machine reamer.

Q:Spindle runout of less than 0.003, the diameter of the cutter size, internal cooling. Excuse me, where is the reason?.

Consider the choice of materials and sizes

Q:NC machining, the speed and feed of the reamer

CNC reamer is generally high-speed steel cutting tools, the line speed is generally around 10-20, according to the diameter of your reamer, you can switch on the basis of cutting speed formula. The feed is generally fed to each turn 0.1mm

Q:What is CNC reamer?

Generally refers to the single indexable blade reamer (currently only international companies only), such as Sweden and Germany is MAPAL indexable single edge reamer, cutting smoothly without vibration, high machining accuracy, reaming allowance, high cutting speed, shape and position error is small, long tool life;But some people put the reamer in the NC machine tool called NC reamer, the scope is big, a reamer, common straight shank machine machine reamers with adjustable pressure, expansion reamer, reamer taper and taper shank reamer etc..

Q:The reamer H7 and H8 are of high accuracy

H7 high, of course

Q:To machining M8, blank hole reamer processing thread with what specifications of the machine (bottom)?

M8X0.75 is in diameter 7.2M8X1 is in diameter 6.9M8X1.25 is in diameter 6.6

Q:The machining center CNC uses reamer to lower the reamer oil. Should the spindle be turned or reversed?

This must be turning!

Q:Mr. Cui, Kong is 9.97. I want to use my 10H7 reamer to reaming the hole with my hand. The book said that small or excessive margin will affect the reaming accuracy, then 0.03 of the margin can also be reaming to hinge it? I don't quite understand why the small margin affects the accuracy of reaming If so, what else would be done with thick hinges and precision hinges?.

Sorry, I just saw your question today. It might delay your work. I'm sorry.1. reaming is mainly to achieve a certain size accuracy, shape tolerances and surface roughness.2. reaming can not or difficult to correct position deviation.3. reaming is the use of multi blade, fixed diameter to ensure accuracy, less margin cutting and appropriate extrusion to improve surface roughness.4. most reamer because of the front angle is smaller, the rear angle is almost zero. The allowance is too long (for example, single-sided 0.015 mm), and it is difficult to cut or strip the excess material.5., if the surface roughness of the previous process is poor, it is difficult to meet the requirements by the extrusion peak.6. reaming can only improve the 1~2 level accuracy. So sometimes to coarse, fine hinge. But it can only reach IT6~7 level.7., when the smaller margin, rolling process can be used to improve the accuracy of the hole. It only causes surface hardening.
